Falling objects, including tools, are a hazard in the construction industry. They can strike workers or equipment as they descend if they are not securely secured, causing injury or death. Even a sturdy helmet will not be enough to prevent head injuries when a metal tool falls from a great height. Any type of falling object, including large power tools and small nuts/bolts, can be a cause for concern. Gravity increases the force of a falling object to the point where it can penetrate a person’s safety equipment, almost like a speeding bullet.
What are conjunctions?
Tool ties are designed to prevent objects from falling. They are used to attach various tools to an anchor point such as a fall arrest system for workers on elevated surfaces. The tie catches the tool if it slips out of the worker’s hand and prevents it from hitting the ground or floor below.
All lashings must be securely attached using a carabiner and a D-ring. If a tool is equipped with a D-ring, it is considered “tie-ready.” Other attachment points include quick-turn and quick-ring attachments, D-ring slings, D-ring and quick-roll strap, and tool lashing attachments. The tool must have at least one opening where a strap can be attached; otherwise, it may not be safe to use when working at heights.
The other end of the lanyard is attached to an anchor point, either on the worker’s body or a nearby structure. If the tool weighs more than five pounds, it should be secured away from the body, such as a wall or railing. If the tool weighs five pounds or less, it can be attached to the worker’s tool belt, belt loops, holsters, or wrist strap. This helps the worker stay mobile in the field. If tools must be secured away from the body, they should be kept in a central location where work is being performed.
There are two types of tool straps: rigid (or fixed length) and elastic (or stretchable) tool straps. Rigid tool straps have a set length, and do not have a drop stop system to prevent the tool from swinging back and forth. Elastic straps use shock absorption to slow the tool’s fall, helping it come to a complete stop.
Both options prevent tools from falling, but elastic straps are usually the best choice for working at heights. They make it easier for workers to collect fallen tools by limiting unnecessary movement. Heavy power tools can swing like pendulums if they are fast enough, which can be dangerous in certain situations. The sudden shock of a fall can also put stress on fixed straps, making them more susceptible to wear.
What are the requirements for fasteners?
The International Safety Equipment Association (ISEA) Voluntary Standard No. 121-2018 specifies best practices for securing tools when working on elevated surfaces.
When selecting a tool strap, all attachments, straps, and anchors must be designed to support the maximum weight of the tool in question. They must also be compatible with the tool. Read the manufacturer’s recommendations for tool strapping to select the appropriate equipment.
The rope should not be longer than is required for the task. The crew should use the shortest possible rope to limit the distance between themselves and the tool. The further the tool falls, the more damage it will cause.
This equipment should also be tested on site before work begins. The tether should hold the tool during a fall without hitting workers or surfaces. The tether should not interfere with the functions of the tool, including locks, switches, and other controls. Workers can also practice retrieving tools after a fall to ensure they remain within reach.
Field workers should be trained on how to use this equipment and the importance of fasteners. If management determines that fasteners are needed, signs should be posted on site to remind workers to use this equipment.
Workers should inspect lashings before and after each shift to ensure they are safe to use. While this equipment tends to be durable with reinforced lashings, the material can wear down over time. D-rings may appear bent, dented, or rusty. Tightening the lashings beyond their maximum limit reduces flexibility. All damaged equipment should be replaced immediately, and damaged items should be taken out of service.
Workers should never keep belts near moving parts or machinery, such as gears, blades, wheels, and belts.
Ties, anchors and accessories should be marked and numbered. It is best to store this equipment in a dry place at room temperature to protect it from damage.
Tool attachments should be included in the company’s safety records. Managers should document the condition, use, and maintenance of this equipment. If an accident occurs, the company can refer to these records to find out what went wrong and make the necessary changes to ensure it does not happen again.
Tools can easily fall out of people’s hands, especially if they are slippery or if the worker cannot grip them securely. But a dropped tool should not cause injury to others or stop work. Workers should be able to quickly pick up the tool using a rope, so they can get back to work as soon as possible.
Attaching tools at high heights increases efficiency and reduces the risk of injury and structural damage.
